STEAM-HAMMER.

SPECIFICATION forming part of Letters Patent No. 754,636, dated March15, 1904.

Application filed August 12, 1902.

To ,aZLwhom it may concern:

Be it known that I, CHARLES EMnRr BIL- -LIN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and Statev ofIllinois, have invented a new and useful Improvement in Steam-Hammers,of which the following is a specification.

This invention relates to steam-hammers. The ob ect of the lnventlon isto provide a construction of steam-hammer which 1s s1m--ple-andeflicient and wherein the operating parts are mounted upon acasting adapted to .be bolted or otherwise secured to the wall of abuilding or to a post, column, or other supporting-stanchion. Otherobjects of the invention will appear more fully hereinafter.

- hereinafter set forth, as shown in the accompanying drawings, andfinally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views andreference-signs appearing thereon, Figure 1 is a view in front elevationof a steam-hammer embodying the principles of my invention; Fig. 2 isaside elevation of the same. Fig. '3 is a view in top plan. Fig. 4 is aview in Vertical central longitudinal section. Fig. 5 is a broken detailView in longitudinal central section of the control-valve. Fig. 6 is aview in transverse section on the line 6 6 of ,Fig. 4 looking in thetransverse section on the line 7 7 of'Fig. A looking in the direction ofthe arrows.

The same part is designated by the same reference-sign wherever itoccurs throughout the several views.

In the ordinary construction of steam-hammers the hammer proper and itsoperating mechanism are mounted upon a very heavy casting,.which formsits frame or support. This involves the necessity of a very heavycasting in order to withstand the shocks due to the operation of thehammer and the operating mechanism of thelatter. A hammer so constructedoccupies considerable space in the ing parts.

shop and is unhandy to shift from one position to another.

It-is among the special purposes of my invention to provide asteam-hammer wherein the hammer proper and its operating mechanism aremounted upon a casting or supporting-framework which may be readilyattached to a wall of the shop in which the device is tobe used or upona column, post, or supporting-stanchion, this being particularlydesirable in the case of small steam-hammers,

. which are useful in most shops for comparatively light work. 7

In the drawings reference-sign A design ates a casting or bracketconstituting the supporting-framework of the hammer and its operat- Thisbracket or casting is-adapted to be bolted or otherwise secured to thewall of the shop in which the device is to be used or to a supportingcolumn, post, or standard,

(indicated at B.) p

Cdesignates the hammer, suitably carried by a stem or shank D, arrangedto operate vertically through a bearing E, formed on or supported by thebracket or frame A. Apiston F is arranged to operate in a cylinder G,suitably supported upon the bracket or casting A, and has its rod Harranged to be connected to the stem or shank D of the hammer, wherebyby supplying a pressure medium to cylinder Gr on one side or the otherof the piston F operating therein the hammer is reciprocated in itsguide-bearing E to accomplish its work. direction of the arrows. Fig. 71s a view in J designates a valve-casing in which is arrangedto operatea valve K, said valve controlling the supply-portL and the inlet-ports MN. The inlet-port M communicates with a passage 0, communicating withthe upper end of cylinder G, and the inlet-port N communicates with apassage P, delivering into the lower end of cylinder G. Communicatingwith the valve-casing is an exhaust-pipe Q, and a supply-pipe Rcommunicates with the supply-port L.

Suitably connected to the stem S of controlvalve K is a rod A, by whichsaid valve is operated. The rod A may be actuated to start up the deviceby means of a hand-lever B,

provided with a detent or catch operating over a toothed segment or rackC in a well-understood manner. Suitably connected to the valveoperatingrod A is a cam-shoe D, operating on a cam-track E, formed on the shankor stem of the hammer, the cam-track E operating to shift the valve ateach limit of stroke of the hammer.

F designates a throttle-valve arranged in the supply-pipe R and whichmay be operated through the rods G H and links J K from a foot-treadle Lor in any other convenient manner, whereby by suitably manipulating thefoot-treadle the supply of operating medium may be cut off.

M designates the anvil, which may be conveniently supported and arrangedin any suitable manner-as, for instance, upon a base N, which isseparate from and independent of the frame or bracket A, whichsupportsthe hammer and its operating mechanism.

If desired, the cylinder G may be provided with a cap P at its upperend, which may be more frangible than the cylinder G, so that in casethe piston F should for any reason exceed its proper length of upwardstroke said cap may be carried away without injuring the cylinder.

If desired, a spring-buffer (indicated at Q) may be arranged to beengaged by a shoulder or collar R on the hammer shank or stem to relievethe shock of the hammer when moving toward its upper limit of movement.

From the foregoing description it will be seen that I provide anexceedingly-simple construction of steam-hammer wherein the hammerproper and its operating mechanism is mounted on or carried by a bracketor framework or the cylinder of the hammer may be formed integrally withsuch bracket or framework, and which bracket or framework is independentof the anvil and its support and may be readily applied or mounted on awall, post, column, or stanchion of a shop or shifted when desired, thussecuring economy in construction, facility in handling, and compactnessof arrangement of the parts.

Having now set forth the object and nature of my invention and aconstruction embodying the principles thereof, what I claim as new anduseful and of my own invention, and desire to secure by Letters Patent,is

1. As an article of manufacture, a steamhammer comprising a frame orcasting having a flat rear portion formed to be secured to a wall orcolumn, and having attached thereto a cylinder, and guides for themovable parts, a hammer, a spring-buffer to limit the upward movement ofthe same, and operating mcchanism for admitting working fluid into thecylinder and reciprocating the 11 ammcr, as and for the purpose setforth.

2. As an article of manufacture, a steamhammer comprising a C-shapcdframe or casting having a flat back portion formed to engage and besecured to a wall or column, a cylinder at the upper extremity of saidframe, vertical guides at the lower extremity in. alinement with saidcylinder, and a hammer guided thereby, and operating mechanism foradmitting working fluid into the cylinder and reciprocating the hammer,as and for the purpose set forth.

3. As an article of manufacture, a steamhammer comprising a C-shapedframe or casting having a fiat back portion formed to engage and besecured to a wall or column, a cylinder at the upper extremity of saidframe, vertical guides at the lower extremity in alinement with saidcylinder, and a hammer guided thereby, and automatic operating mechanismfor admitting working fluid into the cylinder and reciprocating thehammer, as and for the purpose set forth.

4. As an article of manufacture, a steamhammer comprising a C-shapedframe or casting having a flat back portion formed to engage a wall orcolumn, a plurality of bolt-holes therein whereby the same may besecured to the wall or column, a cylinder and valve-gear at the upperextremity of the frame, and a hammer guided in bearings at the lower endof the frame, as and for the purpose set forth.

In witness whereof I have hereunto set my hand, this 7th day of August,1902, in the presence of the subscribing witnesses.

CHARLES EMERY BILLIN.
